Actually parted brakes drive, because the "rm 2" command instantly
removes the partition and saves the changes, and next command mkpart
crashes the app. I expect parted would change the mac or msdos
partition map, so I can change the rest manually. Or even better, that
parted would change msdos by default which is used by kernel by
default (not mac partition)
